Thread: fullscreening the dos window

http://cboard.cprogramming.com/showt...ght=fullscreen

Here's a little more robust version:

Code:

// Simulate ALT-ENTER keystrokes
void AltEnter()
{
    // NOTE: This method only works if the console window has the keyboard 
    //       focus and the user isn't hitting keys on the keyboard.
    SetForegroundWindow(GetConsoleWindow()); 
    keybd_event(VK_MENU, MapVirtualKey(VK_MENU, 0), 0, 0); 
    keybd_event(VK_RETURN, MapVirtualKey(VK_RETURN, 0), 0, 0); 
    keybd_event(VK_RETURN, MapVirtualKey(VK_RETURN, 0), KEYEVENTF_KEYUP, 0); 
    keybd_event(VK_MENU, MapVirtualKey(VK_MENU, 0), KEYEVENTF_KEYUP, 0); 
}//AltEnter

If you're running on an NT based verison of Windows, here is the best way to do it:

Code:

/*-----------------------------------------------------------------------------
NT_SetConsoleDisplayMode - Set the console display to fullscreen or windowed.

Parameters:
    hOutputHandle - Output handle of cosole, usually 
                        "GetStdHandle(STD_OUTPUT_HANDLE)"
    dwNewMode - 0=windowed, 1=fullscreen

Returns Values: 
    TRUE if successful, otherwise FALSE is returned. Call GetLastError() for 
    extened information.

Remarks:
    This only works on NT based versions of Windows.

    If dwNewMode is anything other than 0 or 1, FALSE is returned and 
    GetLastError() returns ERROR_INVALID_PARAMETER.
    
    If dwNewMode specfies the current mode, FALSE is returned and 
    GetLastError() returns ERROR_INVALID_PARAMETER. Use the (documented) 
    function GetConsoleDisplayMode() to determine the current display mode.
-----------------------------------------------------------------------------*/
BOOL NT_SetConsoleDisplayMode(HANDLE hOutputHandle, DWORD dwNewMode)
{
    typedef BOOL (WINAPI *SCDMProc_t) (HANDLE, DWORD, LPDWORD);
    SCDMProc_t SetConsoleDisplayMode;
    HMODULE hKernel32;
    BOOL bFreeLib = FALSE, ret;
    const char KERNEL32_NAME[] = "kernel32.dll";

    hKernel32 = GetModuleHandleA(KERNEL32_NAME);
    if (hKernel32 == NULL)
    {
        hKernel32 = LoadLibraryA(KERNEL32_NAME);
        if (hKernel32 == NULL)
            return FALSE;

        bFreeLib = true;
    }//if

    SetConsoleDisplayMode = 
        (SCDMProc_t)GetProcAddress(hKernel32, "SetConsoleDisplayMode");
    if (SetConsoleDisplayMode == NULL)
    {
        SetLastError(ERROR_CALL_NOT_IMPLEMENTED);
        ret = FALSE;
    }//if
    else
    {
        DWORD dummy;
        ret = SetConsoleDisplayMode(hOutputHandle, dwNewMode, &dummy);
    }//else
        
    if (bFreeLib)
        FreeLibrary(hKernel32);

    return ret;
}//NT_SetConsoleDisplayMode
